APG-2449 in Patients With Advanced Solid Tumors

Inclusion criteria

• Dose exploration stage: non-small cell lung cancer diagnosed by histology and/or cytology and positive for ALK/ROS1 gene fusion (molecular diagnosis confirmed by the investigator) and malignant pleural mesothelioma, esophageal cancer and ovarian cancer. Kind of patients with advanced tumors.

Expansion stage: cohort 1, patients with non-small cell lung cancer who have progressed or are intolerant to TKI therapy, including patients with second-generation ALK TKI, or either ROS1 TKI, or third-generation ALK inhibitor (lorlatinib, etc.) with pFAK expression (pFAK expression is subject to central laboratory results) of about 10 or above; Cohort 2, TKI-naïve patients with ALK/ROS1 fusion gene positive NSCLC. The molecular diagnosis results of the above patients can be confirmed by the investigator.

• Known allergies to study drug ingredients or their analogs.
• Female subjects who are pregnant or breastfeeding, or expecting to become pregnant during the study period.
• According to the judgment of the investigator or sponsor, any symptoms or disease of the subject may endanger its safety or interfere with the safety assessment of the study drug.
